Ruthless Killers<br><br>
From the moment tiny baby piranhas hatch from their microscopic eggs, they come into the world armed and dangerous. Baby piranha will feast on tiny crustaceans, fruits, seeds, and aquatic plants. Once they reach about 1.5 inches in length they begin feeding on the fins and flesh of other fish that wander too closely. As they grow larger they begin to venture out in groups (schools) of about 20 fish where they use a variety of hunting strategies to kill and eat their prey. Heck, they don\'t kill their prey first, they just start eating the victim alive - that\'s what makes them so ferocious. Adult piranha have been known to eat their own babies. Talk about brutal!<br><br>
When a school of piranha are in a feeding frenzy the water appears to boil and churn red with blood. They attack with such ferocity that they\'ve been seen stripping another fish of its flesh so rapidly all that remains is a head with a mouth still gaping to breathe. Piranhas frequently take bites out of each other during a feeding frenzy and are notorious for their cannibalism. Adult piranha will eat just about anything - other fish, birds, and they\'ve been witnessed taking larger prey, such as jaguars and capybaras. They\'ve even been known to take chunks of flesh out of people. Occasionally, cattle that are weak, sick or injured that have ventured into the water to drink have been attacked by a ravenous school of piranhas and completely devoured within minutes. As wicked as it all sounds, piranha have a useful function in the Amazon jungle just like any other predators in the wild. They are part of the checks and balances Mother Nature employs to eliminate the weak and sick so only the strong survive.
